I have a computer that is having problems with a trojan. The DNS settings were being removed every time we booted the computer.

I was able to fix that using combofix, but now when I run Microsoft Security Essentials it keeps coming up with trojan:DOS/Alureon.A and it removes it sometimes, quarantines it another time, but keeps finding it everytime. Sometimes it can't even do anything with it. It's definitions are updated but now it's having trouble updating too. How do I remove the trojan permanently?

I have run Malwarebytes on this computer as well.

Run TdssKiller and Hitmanpro to see if they resolve the Mbr infection
